Mama birds love the Close & Secure Sleeper because it gives baby a soft little "nest" of his own while keeping him or her close by. You can feed, soothe, monitor and bond throughout the night with the reassurance that your little one is snug, secure and safe-thanks to our Airflow design that allows air to circulate around baby. Designed to be easily portable for on-the-go convenience, you can also use the sleeper in the crib to help ease baby's transition from your bed when he's ready to leave your nest.
